Physician perceived barriers and solutions to DASH diet recommendations for hypertension prevention and management
Abstract BackgroundThe Dietary Approach to Stopping Hypertension (DASH) is proven to lower systolic and diastolic blood pressure up to 7.8 and 3.7 mmHg, respectively and is considered first-line therapy per national guidelines. Yet, implementation into clinical practice remains suboptimal. MethodsWe designed a provider survey to identify and characterize physician-identified barriers to providing DASH diet to eligible primary care patients to reduce blood pressure. The survey assessed four domains: (1) provider beliefs/knowledge of DASH benefits (2) patient characteristics influencing likelihood of recommendation, (3) practice barriers to provision of DASH diet advice/education, and (4) resources necessary to facilitate use. We conducted qualitative interviews with 4 primary care physicians and designed a 7-item Likert scale-based survey.Participants: University of Colorado affiliated primary care clinics and School of medicine faculty providers working in Denver metro.ResultsThe survey was sent electronically to 149 providers, with 49 (33%) responders. Most providers (65%) believed DASH diet is as effective at lowering blood pressure as adding a medication for patients with pre-hypertension and established hypertension. Providers identified perceived low patient motivation (88%) and low ability to implement DASH diet into patient’s lifestyle (88%) as patient factors influencing their decision to provide DASH diet education. The most significant practice barriers were lack of time (71%) and lack of patient-directed educational resources (67%). Resources providers would find useful included resources accessible through the electronic medical record, (88%), a dietician (83%), and printed patient education materials (59%).ConclusionMost physicians believe DASH diet is effective at lowering blood pressure. The most common barriers to providing DASH education are low perceived patient ability or motivation, lack of provider time, and lack of patient-directed educational resources. Providers identified that readily available electronic and printed materials and access to dieticians would help improve DASH counseling in practice.
